## What is Oncelet?

When was the last time?

You changed the water filter — when? Got a haircut, oiled the bike chain, called your parents, watered the fern. Oncelet keeps these things on one board and counts the days since each of them.

ONE TAP
Did it again? Tap the button. The counter flips back to zero and the entry goes into history. Tapped by mistake? Undo is right there.

A BOARD, NOT A TO-DO LIST
Nothing is overdue and nothing nags. Pin up to four trackers as large plates at the top; the rest sit in a list below. One glance tells you how long it has been.

YOUR OWN RHYTHM
Every entry is kept with its date. After a few, Oncelet shows how often it really happens: "Usually about 38 days."

REMEMBERED LATER?
Add an entry for any past day, with or without the time. Notes are optional.

WIDGETS
Small and medium Home Screen widgets show the count and record a new entry without opening the app.

REMINDERS, IF YOU WANT THEM
Turn on a reminder for any tracker and choose the interval. They are off until you ask.

YOURS
Syncs through your own iCloud between iPhone and iPad. No account, no ads, no tracking.
